2003 Chevrolet silverado exhaust manifold bolt broke. Less than 100k miles. Costly repair to have the bolt drilled out and replace all bolts and gasket. Exhaust leaks and can hear ticking noise for the first 10 minutes or so after the vehicle is started. Also causes my check engine light to come on, pulling error codes for oxygen sensors.
The truck was purchased the 17th of June and two wks later the service engine light came on and its was real hard to get in 2nd gear. We took it to the chevy dealership and they checked it out for us. The problems are there is no cat converter,two seals and a sensor that needs to be replaced. Not to mention 2nd gear is messed . The service manager told us and gave us the list of things wrong and they are the 2nd gear ,the synchroni,3nd gear,synchroni and the ring in first. All this is to do with the transmission and the cat converter. A and z autos got mad that we took it to the chevy dealer. They keep giving us the run around and have not fixed the truck yet and they still have it at their shop. They will not return our calls .
